One of the most pressing environmental issues we are facing today is climate change. Rising global temperatures, ice caps and glaciers melting, rising sea levels, and increased extreme weather events all point to the Earth’s changing climate and the need to reduce global emissions of greenhouse gases. The warming climate is already having visible effects on the environment, posing significant threats to global biodiversity and human health.
